Boron Removal from Geothermal Water by a Novel Monodisperse Porous Poly(GMA-co-EDM) Resin Containing N-Methyl-D-Glucamine Functional Group

Abstract

Boron removal from geothermal water and its reverse osmosis (RO) permeate was examined by a novel synthesized monodisperse porous poly(GMA-co-EDM) resin containing N-methyl-D-glucamine. The optimum resin concentration was found to be 4 g L⁻¹ and the kinetic data were found to follow a pseudo-second-order kinetic model. According to the correlation coefficients for diffusional kinetic, the rate controlling step was particle diffusion.
